Product Overview

Tag	His
Host Species	Human
Synonym	Killer Cell Lectin Like Receptor K1, Killer Cell Lectin-Like Receptor Subfamily K, Member 1, NKG2-D-Activating NK Receptor, NK Cell Receptor D, D12S2489E, NKG2D, DNA Segment On Chromosome 12 (Unique) 2489 Expressed Sequence, Killer Cell Lectin-Like Receptor Subfamily K Member 1, NKG2-D Type II Integral Membrane Protein, CD314 Antigen, NKG2-D, CD314, KLR.
Background	Killer Cell lectin-Like Receptor Subfamily K, Member 1 (KLRK1) is an activating receptor which has recently generated considerable interest. The most fascinating of these, are a couple of closely related proteins known as MICA and MICB. These are cell-surface molecules distantly related to MHC class I proteins, and their genes have elements of heat shock promoters. Thus, MICA and MICB are expressed in the course of cell stress and are up-regulated in tumor cells and during viral infections. This receptor-ligand combination has a crucial role in the immune response to various pathologies.
Description	KLRK1 Human Recombinant expressed in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 386a.a. (73-216a.a.) and having a molecular weight of 43.9kDa (Molecular size on SDS-PAGE will appear at approximately 40-57kDa). KLRK1 is expressed with a 242a.a. hIgG-His tag at C-Terminus and purified by unique purification methods.

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
